Different things. Apparently there's two of them going around. The other one only includes people you've met in person, but this one includes everyone. I like this one rather bet, partly because the questions are better, and partly because whether I've met someone in person has relatively little bearing on how well I know them.

I did the other one with people I had had more than one or two conversations with - i.e people I knew vaguely well. This eliminated the hundreds of random people who I don't know very well from LJ or BiCon or whatever.

I also got to eliminate people with multiple journals, some people have 3 or 4 journals and I think one of them has 5...

It does! I know it does, because I remember having to learn about bits of it when I was about 15 or so. I can't remember any of it anymore though, of course. All that's left is a vague recollection of learning to label various thinga on a map, and the possibility that there might have been some sort of agriculture involved.
